The chapel has three rows with 10 seats on either side of the main aisle. So while 600 guests were invited, only about 60 had a perfect view of the bride and groom exchanging vows.
The wedding ceremony included a fiery speech from U.S. pastor Michael Curry, along with performances of "Stand by Me" and "This Little Light of Mine" by a gospel choir.
Prince Harry's father, Prince Charles, walked Markle down the aisle after her father, Thomas Markle Sr., could not make it to the wedding. However, her mother Doria Loyce Ragland was in attendance. Ragland sat in the first seat in the second row on the left side of the church.
Scroll on for a look at where some of the most well-known guests were sitting.
Queen Elizabeth II and her husband, Prince Philip, the Duke of Edinburgh, sat in the first two seats in the second row on the right side. Their youngest son, 54-year-old Prince Edward, the Earl of Wessex, sat next to his father.
Notably, there was an empty seat in front of the Queen. This was reportedly so the Queen had a perfect view of the wedding ceremony.
The first row on the right was filled with familiar faces. Prince Harry's brother and Best Man, Prince William, sat in the second seat.
His father, Prince Charles, who walked Markle down the aisle, sat next to William. Next was Charles' second wife, Camilla Parker Bowles, the Duchess of Cornwall; William's wife, Catherine, the Duchess of Cambridge, sat next to Camilla; Charles' younger brother Prince Andrew sat next to Catherine; and, Andrew's daughters, Princesses Beatrice and Eugenie, sat next to them.
Anne, the Princess Royal, Queen Elizabeth II's only daughter, also sat in the second row, between The Lady Louise Mountbatten-Windsor and Vice Admiral Sir Tim Lawrence, reports the Daily Mail. Lawrence is Anne's second husband.
Anne's son, Peter Phillips, sat next to Lawrence. Her daughter, Zara Tindall, sat in the first seat on the third row on the right side.
Doria Ragland, Meghan's mother, was at the wedding. She sat in the first seat in the second row on the left side. In a 2014 blog post for her now-defunct site The Tig, Markle said her mother served as her role model.
"She will swivel her hips into the sweetest little dance you've ever seen, swaying her head and snapping her fingers to the beat like she's been dancing since the womb. And you will smile. You won't be able to help it. You will look at her and you will feel joy," she wrote. "I'm talking about my mom."
Serena Williams and her husband, Alexis Ohanian, had seats with great views of the ceremony. They say in the third row on the left side, where Markle's other celebrity friends sat.
Williams wore a pink Versace ensemble for the service, with her hair in a pony tail. She was originally supposed to play at the Italian Open, but she skipped it to have more time to prepare for the French Open. This also gave her a chance to attend her friend's wedding.
Williams sat next to Abigail Spencer, an actress who appeared on Suits with Markle. She also appeared in Mad Men, Cowboys & Aliens, This Is Where I Leave You and This Means War. She now stars on NBC's Timeless, although the show is awaiting renewal news.

George and Amal Clooney sat in the third row on the left side, between Suits director Silver Tree and Lady Carolyn Warren, a racing manager known to the Queen, according to the Evening Standard. Like Winfrey, Amal Clooney, a human rights lawyer, wore a Stella McCartney outfit. Her yellow ensemble nearly stole the show from the bride.
